Sgt. Patrick Manley said a large amount of shingles -- upwards of a pallet’s worth in each instance -- were taken. In at least one case, the lumberyard’s forklift truck may have been used to grab a full pallet, he said.

Police in Springfield and West Springfield are probing similar lumberyard thefts, Manley said. Police in those communities were not immediately available for comment.

The East Longmeadow thefts were reported on the mornings of June 20, June 24 and July 6, Manley said. During each incident, the lock that secures the lumberyard’s gate was removed and the chain was put back.
